Shadow options are not showing
I think the youtube video you are referring to, in commenting another answer, was realized using an older version of blender. I tried an old 2.80 I had installed, and it shows the options you're missing (they're missing in my 2.82a, too):



Those options are gone in 2.81. This release log (related to python API usage of those options) points this out and cites a developer change in code_ https://wiki.blender.org/wiki/Reference/Release_Notes/2.81/Python_API#EEVEE

Anyway it is always possible to download any previous version as a zip package, and just extract them in a folder and run them launching the blender file. You find all released versions here: https://download.blender.org/release/
